Alanine aids the body during intense aerobic activity, when muscle protein is used to help produce energy. Another noted benefit is its ability to protect against the build-up of toxic substances released in the muscle cells when protein is broken down to quickly meet energy needs. It also helps regulate and maintain healthy blood sugar levels.
When taken as a supplement, alanine is released by the muscles into the bloodstream. It then evolves into glucose and is released into the blood plasma. Because of its ability to stabilise blood sugar levels during exercise, alanine can help athletes with their endurance at competitive intensities.
Two grams of L-alanine is normally consumed roughly half an hour before working out.
